Lab-Grown Diamond Side Stones / Business sourcing
Triangular brilliant-style side stones for deliberate center framing, with edge shape and tip placement defined by your drawing.
Preferences are a brief, not a live inventory selection.
A product brief, not just a grade list
Trillion-cut lab-grown diamond side stones introduce a triangular outline that can point the eye outward from a center setting. Small differences in edge curvature, tip shape and proportions can change the resulting layout, so triangular shape names should be supported by an actual contour reference. State whether the intended edges are straight or gently curved, how the tips should face, and what dimensions the seats require. Treat the left and right stones as a design pair while recording them individually. Proposed supply, cutting style, documentation and setting compatibility need project-specific review before this specialist shape is adopted for a custom piece or repeat collection.
01 / Define the actual requirement
Separate the product description, sample values and information that must be confirmed for the actual selected goods.

| Cutting style | Trillion / triangular brilliant-style request; exact pattern confirmed |
| Illustrative size request | 3.00 × 3.00 mm face-up envelope; sample drawing only |
| Depth / corner details | Define with the setter and the proposed stone selection |
| Pair orientation | Tip direction and inward-facing edge shown in the layout |
| Weight record | Per-stone weight and pair total remain separate |
| Growth method | Confirm CVD or HPHT for the proposed goods |
| Documentation | Confirm the available laboratory report or batch documentation |
| Post-growth treatment | Confirm disclosed treatment information for the proposed goods |
| Order unit | Each or matched triangular side pair, subject to sourcing confirmation |

Send contour and direction references for each triangular position.
02 / Choose against the design
Use these product-specific checks to make your quotation request more precise.
A triangular envelope does not settle the contour. Show whether the three sides should be straight or rounded, and retain that drawing with the request so a proposed trillion can be compared against the intended silhouette.
The triangle’s rotation changes its relationship to the center and shoulder. Number the positions in the design, showing the inward edge and outward tip rather than relying on a general instruction to supply a matching pair.
Corner and tip geometry should be considered in the setting plan. The sourcing brief should explain the seat and protection requirements, allowing the final selection to be reviewed by the person who will set the stones.
Look at edge shape, proportions and the way light returns from both stones in consistent conditions. Similar measurements or grades alone do not establish the visual balance of the triangular frame you are building.
03 / Plan from the finished design
The finished setting or production workflow determines which measurements and matching decisions belong in the enquiry.
APPLICATION 1
A trillion pair can be considered around a cushion center when the design calls for triangular side geometry. Show the cushion contour, the inward triangle edge and the outward tip direction together, then have the setter review the proposed three-stone arrangement.
Brief This Application
APPLICATION 2
A loose triangular pair can be reviewed over the drawing before the mount is fixed. Compare edge curvature, tip direction and face-up proportions in the intended positions, and ask the setter to confirm how the selected points will be supported.
Brief This ApplicationADDITIONAL DESIGN USE
An individual triangular stone or counted group can form a strong directional motif. Define the outline and rotation of each position, and distinguish repeated identical triangles from deliberately contrasting pieces in the design.
Brief This Application04 / Your buying model
Use a triangular silhouette with deliberate rotation and edge shape rather than a generic accent description.
Include in the RFQ: Send contour and direction references for each triangular position.
Create a balanced pointed side frame around the client’s selected center.
Include in the RFQ: Include the center dimensions, side envelope and setting protection plan.
Translate tip and edge geometry into a workable mount before final stone approval.
Include in the RFQ: Provide seat dimensions, depth limits and agreed visual matching requirements.
05 / Qualitative procurement scenarios
Use a specific business scenario to prepare an enquiry. These examples do not assert national preferences, market size or confirmed orders.
| Market | Buying scenario | RFQ focus |
|---|---|---|
| United States | Geometric side-stone bridal proposals | Triangular contour, center reference and tip orientation |
| United Kingdom | Design-led bespoke jewelry | Edge curvature, protective setting and approval reference |
| Australia | Small geometric collection development | Sample envelope, directional layout and repeat criteria |
For a US-facing custom bridal proposal, specify the triangular sides as a separate selection task. The center outline and triangle rotation should appear together in the brief. A broad carat target does not resolve the geometric information needed for the setting.
A designer and setter working together on a triangular accent can agree the contour before the stone search begins. Distinguish straight-edged from curved-edge references and review the actual proposal. The scenario is design guidance, not a national statement about shape popularity.
For a sample collection, record which triangular positions repeat across different pieces. Agree the accepted envelope and the comparison process for later supply groups. Establish availability and timing for the actual project rather than assuming a permanent catalogue stock lane.
06 / A practical comparison
Compare the properties that change the purchasing decision, then review the actual selected stones or parcel.
| Buying point | Trillion / triangular | Pear-shaped |
|---|---|---|
| Outline | Three-sided triangular contour | One pointed end with rounded opposite end |
| Direction information | Triangle rotation and inward edge | Point direction and long axis |
| Fit description | Envelope, edge curves and corners | Length, width, shoulders and tip |
| Pair review | Triangle proportions and mirror placement | Pear outline and mirror placement |
| Design choice | When a triangular geometry is intended | When a pointed rounded silhouette is intended |
08 / Before you source
A triangular outline does not define the complete facet arrangement. State the intended cutting style and show the contour reference. The term trillion is used here for a triangular brilliant-style sourcing brief; the proposed stones still need their actual pattern and outline confirmed.
Provide the contour you want, because both the edge shape and overall proportions affect the design. Do not assume that equal length and width create the same triangular silhouette. Review the actual proposed stones against the reference before approving their fit.
It depends on the center and the ring architecture. Show which edge should face the center and which tip should point toward the shoulder. A numbered layout gives the supplier and setter a shared reference without implying that one orientation is universally correct.
Discuss the setting and corner requirements with your setter before final selection. Include those constraints with the sourcing brief and have the proposed geometry reviewed for the actual mount. A product photograph cannot establish a particular setting’s protection or fit.
State whether the design needs one stone, a matched side pair or a counted group. Specify dimensions and orientation for every required position. Availability, documentation and commercial terms should then identify that requested unit rather than leaving the order format ambiguous.
Compare the contours, rotation, proportions and face-up appearance in consistent viewing conditions. Keep the individual dimensions and weights as well as the intended pair layout. Similar grade descriptions do not remove the need to approve how the two triangles work together.
09 / Prepare the next conversation
Start with the fixed requirements and explain where the sourcing selection can vary.
Send contour and direction references for each triangular position.
